Oil Pump Gears Set for 22163

The MOROSO Oil Pump Gears Set for 22163 is a direct replacement gear assembly designed for engine oil pump systems requiring precision internal components. This kit includes the complete gear set along with the necessary o-ring seal, providing everything needed for a full restoration or repair of your oil pump assembly. Built to OEM specifications, this replacement gear set ensures consistent oil delivery and system pressure critical to proper engine lubrication and longevity.

Oil pump gears are subject to continuous wear under high rotational speeds and pressure cycling. MOROSO manufactures this gear set to maintain tight tolerances and proper meshing geometry, preventing internal leakage and maintaining flow rate across the engine's oil galleries. The included o-ring seal addresses a common failure point in pump rebuilds, eliminating the need to source seals separately. Whether rebuilding a pump following engine overhaul or addressing low oil pressure symptoms, this complete kit reduces complexity and sourcing time.

This gear set is suited for engine builders, restoration shops, and knowledgeable enthusiasts performing pump service on compatible platforms. Oil pump replacement is standard during full engine rebuilds and becomes necessary when metal debris indicates internal wear or when pressure testing reveals insufficient flow. MOROSO's direct-fit design means no custom fitting or machine work required—the gears arrive ready for installation into prepared pump housings.

Model 22163 represents a specific pump design found across various engine applications. Confirming fitment with your pump casting number before ordering ensures proper engagement and pressure characteristics.
